Senior Design I Peer ReviewJanuary 20th, 2006PO6208 – ARC Works Sports Bottle

Sponsor: ARC Works of Monroe County

Team Members: Team Leader George Gooch, Chris Donati, Drew Stone-Briggs, Hui Kim, Mike Hayden, Mike Levis, Jeff Coppola, Bill Lucas

Mentors: Dr. DeBartolo (ME) and Dr. Marshall (IE)

Project Overview The Following is a Basic Overview for the

Purpose of the Project: Faster and more automated production Less rejected assemblies More convenient and ergonomic work stations Better inventory management

Background, to Date Met with sponsor to discuss objectives Created needs assessment based on meetings Began conceptualizing solutions

Design Team - ‘Brainstormed’ different options for each process Inventory Management Team - Began working with inventory

program

Project Overview (Cont.) Basic Assembly

Finished Enclosure

Components

Closure (Various Sizes) Adapter Straw (tube)

(Various Lengths)

Project Overview (Cont.) 1st Operation: Straw Cutting

Process Machine

10 Straws at once are inserted into the top of the automated straw cutter. The machine cycles, cuts the straws and they drop through into a box.

Project Overview (Cont.) 2nd Operation: Adapter / Closure Insert

Process MachinesClosures are placed in the bottom fixture and Adapters are placed in the top fixture of one of two style manual presses. The presses are cycled to create the Closure / Adapter Sub-assembly.

Project Overview (Cont.) 3rd Operation: Final Assembly Press

Process Machine

Closures / Adapter Sub Assemblies are placed in the top fixture of the automated press. Straws are placed in the bottom fixture. The machine is cycled to create the final assembly.

Design Ideas for the Closure Tube Assembly Process

Improve tube cutter loading Combine all assembly steps Increase productivity using automated

feeders Improve ergonomics & safety Add electronic parts counter

Tube Cutter Improvement

Modifying vs. replacing existing equipment Standardizing machine components Expanding the capacity of the tube holder Adding electronic parts counter Improving ergonomics

Tube Cutter Improvement

Manual Tube Feeding Concept

Tube Cutter Improvement

Discussion: Methods for improving throughput,

especially loading of tubes into cutter Manual vs. Automated Increase batch size

Assembly Process Improvement

Pin Style Automated Press Discussion: Pin tube support

Sliding Adapter Fixture Press Discussion: Closure Interference,

Fixture Alignment, Adapter Orientation

Assembly Process Improvement Two Stage CTA Press

Discussion: CTA Removal, Rotation

CTA Process w/ Magazine Feeder Discussion: Alignment

Feeding Concepts Automated Feeding

Discussion: Cost, Complexity, Durability, Clip Manufacturability

Also… Closure?

Feed Escapement

Tube Adapter

Current Inventory Issues Sponsor’s concerns include:

Tracking sub-assemblies through the system Running different types of reports such as sales and

inventory The ‘Writing Assistant’ function of Great Plains Cycle counts Using Great Plains to help with Safety Stock and reorder

points Inputting data as a transfer of materials rather than an

adjustment Subtracting on-hand components from the system when a

kit is completed Utilizing the software to set up a backorder system to fill

shorted kits

Current Inventory Issues

Discussion:

Metrics to weigh improvements against

How to relate this issue to IE criteria vs. just teaching them how to use the system

How much time should we put into learning the system vs. the amount we can actually help them in a way that is significant in our senior design

Goals Desired Outcomes – Stage 1 (Winter)

Develop an understanding of areas needing improvement Finalize design concepts that meet customer goals Learn the current inventory management system Come to an acceptable design

Develop project BOM and estimated costs

Desired Outcomes – Stage 2 (Spring) Faster production by the ARC Works team Less backorders and established safety stock Fewer rejects Higher satisfaction of workers
